Inspiron 13 5378 2-in-1, 100% disk usage, Windows 10

Agreed!!  I bought two laptops from Dell this year and both have this problem.  The first one the Dell team actually fixed after about (literally) 20 hours on the phone over six days.  They did not charge me.  The second laptop had the SAME problem and they offered no assistance unless I bought their extended warranty.  Such a rip off.  Almost $2K I spent with this company and BOTH devices were unusable as sold....  I wish I could scream it from the rooftops to warn others.  I don't remember all the things they did to try to get the first laptop running again, so I'm stuck with a brick.  I would return it, but it was shipped to my daughter at school and by the time she had given up on it and brought it home for break it was too late.

I have Dell Inspiron 15 5000.

To solve this issue, I did 2 things:

1 - updated Windows to 10.0.17134 (took a while).

2 - disabled SmartByte Network Service and Rivet Dynamic Bandwidth Management Service.

So far, so good. Task Manager still reports high % for disk after restart, but after a couple of minutes it drops down to almost zero and stays there.

For me, after a good month's search, the trick was to remove the Skype app; I had the desktop Skype application installed, but some Windows update (probably the October major rollout) installed the Skype app too. After removing the Skype app, disk usage went straight away down to normal and the PC is usable again.

... removing Skype App finally was not the end of the line. The real cause lied in security misconfigurations of various DCOM services, introduced when the October 2018 update was installed. Mostly had to do with the RuntimeBroker DCOM service, but a couple of other services were affected too.

The documents in https://answers.microsoft.com/en-us/windows/forum/all/multiple-distributedcom-errors-system-freezing-etc/3f4263ae-abdb-441c-8fce-71b70abbe349 and https://www.itexperience.net/2018/12/02/event-id-10016-fix-the-application-specific-permission-settings-do-not-grant-local-activation-permission-for-the-com-server-application-with-clsid/ give walkthroughs to solve the problem. Note that the respective processes may need to be repeated for DCOM services that are failing due to permissions.

I also have same laptop ... facing this issue in new Dell Laptop . 

And these people are saying its not covered in default warranty . 

very Pathetic service from Dell . 

I will try options mentioned in this page ..

I have a Dell G7 that I bought recently. I was noticing occasionally it would go into a spiral of 100% drive usage getting slower and slower until it just more or less had frozen and I had to reboot.

Discovered the offending program was pcdrwi.exe, which is actually part of the Dell SupportAssist. Uninstalled that and have been doing fine since.

Hey Everyone,

I have had this same problem for nearly two years.  Like most of you, I also tried every remedy I could find—but nothing worked--including killing services, reinstalling the OS, updating Windows, etc.  It finally got to the point where my hard drive continued to spin at 100% and wouldn’t ever settle to a usable state.  Dell’s response to the problem is laughable—all the customer’s in this forum started experiencing this problem at the point of unboxing—so it’s not malware, unless it was installed by Dell.  Probably just as laughable were suggestions to uninstall certain applications.  Why the **bleep** would I spend a grand on a new laptop just to limit the applications that I can use?  That makes zero sense.   The bottom line: These laptops should work as configured—period. 

Anyway, I have found a solution to this issue that works 100% of the time.  Although, it may not be for everyone, simply reformat your hard drive and install Linux.  The hardware is solid and runs Linux like a champ,  it doesn’t contain any of that Dell bloatware, and you'll no longer have a $1000 brick.  If I ever run into any applications in which I need to run Windows—and there shouldn’t be many, I’ll simply install a clean version in a virtual machine—but I won’t have Windows be the base OS, and I refuse to buy some crappy dell service plan to “fix” the problem.

mechanical hard drives have this.  When you move to SSD it goes away.

You can also install UBUNTU alongside windows 10 and dual boot.

Hello
stopping the windows search did the trick for me
It's an (older) Dell Latitude E6320 with a standard HDD (non-SSD) on which I recently installed windows 10.

I too have experienced this issue with an 8930 desktop. It started when I first bought the system several months ago and I was able to resolve it by changing a setting in the Intel Rapid Storage Technology application.

A few days ago the Dell Support Assistant indicated the Rapid Storage Technology needed updating so I allowed it to perform the update. After completion, I started to experience the C: drive reaching 100% utilization again and I recalled the steps to correct it.

1. Open Intel Rapid Storage Technology Application.
2. Click on the Performance button.
3. Click on the "Disable" link for "Link Power Management". (After you do that the "Enable" text will become a link.)
4. Restart the computer to activate the new settings.
5. After restarting, verify using Task Manager and Resource Monitor that the C drive no longer pins at 100%.

I hope this fix helps those experiencing the problem as I know it can be frustrating waiting for what should be a very responsive machine open the application you clicked several seconds ago.

I was searching online and found you tube video by Dell on 100% usage.

For me it turned out to be plugins on Chrome browser, once disabled or removed disk usage back to normal.
